面向云制造环境的制造行业知识资源管理技术研究

Technology of Knowledge Resources Management in Manufacturing Industry in Cloud Manufacturing Environment

分析了云制造的特点以及知识管理在云制造全生命周期中发挥的作用,在此基础上设计了一套适合云制造环境的知识资源管理系统框架,采用本体的相关方法构建了制造资源的统一语义模型,解决了制造资源异构、多样、粗粒度的问题。综合分析以往概念相似度方法的基础上提出了基于语义相似度的服务匹配算法。最后开发了相应的原型系统进行了验证。

The paper,based on the analysis of the characteristics of cloud manufacturing and the role of knowledge management in the whole life cycle of resources services,designs the framework of knowledge management system for cloud manufacturing environment,builds the unified semantic model for manufacturing resources and solves the problems of heterogeneity,diversity,and coarse grain of manufacturing resources by using ontology method.Besides,it puts forward the service matching algorithm based on semantic similarity through the comprehensive analysis of previous concept similarity method and finally verifies the prototype system thus developed.
